Glad I could help! Don't know if you know or not (by your suprise I'd say you do) but to be safe- They always ask if it's anyone's birthday (then everyone sings happy birthday) and anyone's anniversary or other "special occasion." Make sure to get there early too, to the prestage area, not sure about the last time we were there, but there used to be a woman with a BUNCH of tropical flowers that she would give on a first-come-first-serve basis and attach them to the women's head depending on their status... One side would mean they're single and the other taken. Granted this was at least a year and half BEFORE the switch over, but who knows, couldn't hurt. It's so pretty in the area too, great for pictures.
Good luck with your surprise, and CONGRATS ON THE WEDDING (whenever it may be.)
